ln explaining the invention in detail, it can be readily discerned that the said invention is capable of many equivalent embodiments of which the preferred are herein depicted and described.

In order to utilize the disclosed invention, it is essential that the ball teeing means be fixedly mounted with respect to floor 101 and operatively linked with a ball receptacle 102. A conventional type ball dispensing means 117 can be used in conjunction with said ball receptacle if required.

l. First Embodiment (see FIGS. 1, 2, 3, 6, and 7) The ball teeing means 100 is composed basically of a base means and a ball elevating means. The base means is defined essentially by cup assembly 104 which a mounting plate 105 is fixedly secured. Said cup assembly 104 has a ball inlet aperture 106 located within its cylindrical sidewall for mounting of ball receptacle 102 in depending relation therefrom and in registry with said aperture 106, an opening within the bottom for the journalling of both the upper portion of rack 110 and tee 107 which exists as a flexible material such as a plastic tube, and an opening 108 at the top to provide for ball exit when placed in registry with the opening within said floor 101.

Tee 107 is fixedly mounted to the top of said rack 110 which is reciprocably mounted within the bottom opening of said cup assembly 104. Centrally and fixedly mounted to the top of said reciprocably mounted rack 110, and in depending manner within the central opening of said tee 107, is the ball sensing means such as photoelectric switching sensor lens assembly 109. The fiber-optic light guide 114 of said sensor is disposed downwardly through and emerging from the bottom of said rack 110, thus providing accessibility for connection to the light source-photocell unit 126. Said unit 126 is in turn connected to the photoelectric proximity switch 127. The bottom end of said rack 110 contains a two-way cam 121 disposed on the non-toothed side in depending manner therefrom.

Brake-gearmotor 112 is fixedly mounted to the back side of mounting plate 105 with its rotatable shaft 115 protruding through and journalled within said mounting plate. Fixedly mounted on said shaft 115 is drive gear 111, which is drivably engaged with said reciprocally mounted rack 110. Shaft 116 journalled within flanged guide roller 113 is fixedly secured to mounting plate 105. Said flanged guide roller 113 is rollably engaged with the non-toothed side of said rack 110. The center distance between shafts 115 and 116 must be such that rack 110 can be reciprocated freely without binding between said gear 111 and said flanged guide roller 113.

On the lower portion of mounting plate 105, adjacent to the non-toothed portion of rack 110, are located three position sensing switches. The lowermost position sensing switch 123 is fixedly secured to mounting plate by means of bracket 122. Said switch is directly opposite the two-way cam 121 when rack is at its lowermost position. The intermediate position sensing switch 124 is fixedly secured to mounting plate 105. Said switch 124 is located directly above and removed from switch 123 by an amount equivalent to the distance the rack 110 must rise to present ball 103 in position for execution of fairway shots by the golfer. In this position the relationship of the ball with respect to the artificial grass would be comparable to a ball lying on the fairway turf of an outdoor golf course. The uppermost position sensing switch 125 is secured to mounting plate 105 and located directly above said switch 124 by an amount equivalent to the average height a golfer would tee up a ball above said fairway shot position so as to execute tee shots such as encountered on a golf course. All of said switches are transversely positioned adjacent to said rack 110 such that they will be actuated when two-way cam 121 assumes a position opposite the roller type actuator of anyone of said switches.

The ball dispensing means 117 is of the conventional commercially available type and is positioned with respect to floor 101 as shown in H6. 1. Fixedly mounted adjacent to said ball receptacle or said ball dispensing means is the vend initiating means such as monetary acceptor unit 118. Said monetary acceptor unit is commercially available and can be obtained to handle either coins or paper money. Also, fixedly mounted adjacent to said monetary acceptor unit 118 is control panel 119, which contains a plurality of pushbutton control switches.

Intermediate said ball dispensing means 117 and said ball teeing means 100 is a ball receptacle 102 functional in conveying balls from said ball dispensing means to said ball teeing means on demand. Said ball receptacle 102 is mounted to the lower portion of said ball dispensing means 117 and is inclined downwardly toward said ball teeing means wherein it mounts within opening 106 of said cup 104.

Floor 101 at the tee line area is surfaced with articifial grass carpet 120 similar in appearance to grass found on golf course fairways or driving tees. Said grass carpet 120 has an opening in alignment with opening 108 of cup 104 to allow ball 103 to emerge when tee 107 is elevated to ball hitting position.

With reference to the drawings, it is readily discerned that the gearmotors, switches, solenoid, photoelectric proximity switch, counter, monetary acceptor unit and the punched tape programmer located within controller 128 are commercially available components. The photoelectric proximity switch is available having both a momentary and maintained output arrangement. Units having provisions for a momentary signal output are known as pulse-stretcher types wherein the output pulse can be either lengthened or shortened regardless of whether the ball remains within the proximity switch detection field for prolonged periods of time.

Tee Shot" and Fairway Shot selection can be accomplished either manually by pushbutton control or automatically through programming means such as punched tape control. For the practice of golf shots the golfer depresses either the Tee Shot or Fairway Shot" selection pushbuttons, depending upon which type of shot said golfer wishes to practice. When the Fairway Shot selection is chosen, the ball teeing means will, when operative, elevate the ball to a position such that said ball can be hit by standard iron clubs under conditions similar to those encountered when hitting fairway shots on a golf course. When Tee Shot" selection is chosen, the ball teeing means will, when operative, elevate the ball to a position such that said ball can be hit by the driver or number one club.

The ball teeing means depicted in FIGS. 2 and 3 may be readily modified by the following methods: (1) An instant start-stop type motor may be used to replace the brake-gearmotor,'thereby eliminating the need for a brake; .(2) A clutch-brake gearmotor in which the motor is made to continuously rotate, can be used in place of the brake-gearmotor. The control'circuit can be modified so that the ball elevator means can be moved by disengaging the brake and engaging the clutch, and stopped. by disengaging the clutch and engaging the brake; and (3) The brake-gearmotor can be replaced by a clutch-gearmotorin which the motor is made to continuously rotate. The ball elevator means can be moved and stopped by simply engaging and disengaging the clutch. Since there is no means available for braking the ball elevator means in this method, the position sensing switches can be adjusted to compensate for any over-travel. Due to gearhead torsional resistance, the ball elevator means will hold its position when said gearhead ceases rotating upon clutch disengagement.

FIG. 7 depicts the electrical controls set on the Golf Practice" with Fairway Shot selection as the mode of operation for the first embodiment. This means that momentary depressing of the Golf Practice" pushbutton PB-l will energize latch relay coil D to close contacts D1, D2, D4, D5, D11 and and open contacts D3, D6,D7, D8, D9, and D10. Momentary depressing of the Fairway Shot pushbutton PB-4 will convey a signal through K3 and D4 to energize latch relay coil L to close contacts L1 and opencontacts L2. Also, said signal will travel through contacts D5 to energize latch relay coil C to close contacts C2, C3, and open contacts Cl.

;Next, upon placement of the proper amount of money in the monetary acceptor unit 118, thevend will be initiated causing contacts K1 and K3 to open, and contacts K2 to close. Opening of contracts Kl will cut off power to the "Golf Practice" and Golf Game" selection branch circuit. This means that after the vend has been ititiated the golfer no longer has the choice of switching between said selections. The purpose of open contacts K3 will become apparent during the discussion related to the function of switching selection from "Tee Shot" to Fairway Shot". Upon closing of contacts K2, power will be provided to the motor control circuit to effectuate reciprocation of tee 107.

Before initiation of said vend, tee 107 will be in the elevated position with no ball thereupon. Immediately at start of ve nd, contacts K2 will close to provide power to terminals 7 and 8' of the photoelectric proximity switch. With no ball on said tee, contacts A2 will be in the closed position for directing power through switch contacts 123A to brake-gearmotor 112 to drive the ball elevating means downward. Tee 107 will therefore decend until two-way cam 121 actuates switch contacts 123A open to terminate power to said brake-gearmotor and stop said tee in the lowermost ball receiving position. While in this position, a ball from ball receptacle 102 will be automatically released to gravitate upon tee 107. Gravitation of said ball upon said tee will cause the photoelectric proximity switch to become activated and induce contacts Al to close and contacts A2 to open. Closing of said contacts A1 will cause power to flow through contacts C2, L1, and switch contacts 124A to brake-gearmotor 112. Energizing of said gearmotor will cause the ball elevating means to rise until cam 121 actuates said switch contacts 124A open. This will cause power to be terminated to said gearmotor 112 such that tee 107 is stopped at the intermediate ball hitting position common to Fairway Shots.

Upon dislodging of ball 103 from tee 107, the photoelectric proximity switch will operate to provide a pulse through terminal 9, open contacts A1, and close contacts A2. Said pulse from terminal 9 will be fed to the ball feed counter module 129 to register a count therein. Said contacts A2 will cause power to flow through switch contacts 123A which are closed when tee 107 is in the elevated position. Said power will in turn operate to reverse the direction of gearmotor rotation to drive the ball elevating means downward. Tee 107 will be lowered until two-way cam 121 contacts and opens said switch contacts 123A to terminate power to said gearmotor and again stop said tee in the lowermost ball receiving position. While in this position, a ball from ball receptacle 102 will be automatically released to gravitate upon tee 107. Gravitation of ball 103 upon said tee 107 will again cause it to rise. Cited mode of operation for lowering andv elevating said tee will prevail on a repetative basis as described, supra. As previously indicated, a pulse will be fed to the ball feed counter module every time a ball is dislodged from said tee. Said plurality of pulses will be registered and when said count reaches the preset count, said ball feed counter wil release a termination pulse to the monetary acceptor unit to terminate the vend. In so doing, contacts K2 will open to terminate power to the controller and to the photoelectric proximity switch.

This means that when the last ball of the vend is dislodged from the tee, contacts A2 will close slightly sooner than or at approximately the same instant contacts K2 open so that little or no power can be conveyed to the gearmotor to lower the tee. Therefore, at the initiation of a new vend, the tee will be in the elevated position. If desired, the said tee can be made to stop at the lowermost ball receiving position after vend termination by adapting minor control circuit modifications.

Golf Practice" with Tee Shot selection is ob-' tained by first momentarily depressing PB-land then PB-3. By reference to FIG. 7 it is readily discerned that depressing of PB-3 will energize latch relay coil C to close contacts C1 and open contacts C2 and C3. Also, latch relay coil L will be energized to open contacts L1 and close contacts L2. The remainder of the circuit will be in the condition dipicted in FIG. 7.

Now, upon placement of the proper amount of money in the monetary acceptor unit 118, the vend will be initiated causing contacts K1 and K3 to open, and contacts K2 to close. Opening of contacts Kl will cut off power to the Golf Practice and Golf Game selection circuit so that the golfer cannot switch selections after the vend is initiated. Closing of K2 will direct power to the motor control circuit to effectuate reciprocation of tee 107.

Immediately at start of vend, contacts K2 will close to direct power to terminals 7 and 8 of the photoelectric proximity switch. With said tee 107 initially in the up position with no ball thereupon, contacts A2 will be in the closed position thus directing the power through switch contacts 123A to brake-gearmotor 112 to drive the ball elevating means downward. Tee 107 will therefore be lowered until two-way cam 121 actuates switch contacts 123A open to cut off power to said brakegearmotor and stop said tee in the ball receiving position. In this position a ball will be provided from the ball receptacle 102 to gravitate upon said tee. This will cause the photoelectric proximity switch to become activated and induce contacts Al to close and contacts A2 to open. Closing of said contacts Al will cause power to be directed through relay contacts C1 and switch contacts 125 to energize brake-gearmotor 112. Said gearmotor will cause the ball elevating means to rise until two-way cam 12] actuates switch 125 open. Opening of said switch contacts will cut off power to said gearmotor such that tee 107 is stopped at the uppermost ball hitting position common to Tee Shots.

Upon dislodging of said ball 103 from tee 107, the photoelectric proximity switch will operate to provide a pulse through terminal 9, open contacts A1, and close contacts A2. Said pulse from terminal 9 will be fed to the ball feed counter to register a count therein. Said contacts A2 will cause power to flow through switch contacts 123A which are closed when tee 107 is in the elevated position. Said power will operate to reverse the direction of gearmotor rotation to drive the ball elevating means downward. Tee 107 will be lowered until two-way cam 121 contacts and opens said switch contacts 123A to cut off power to said gearmotor and stop said tee in the lowermost ball receiving position. While in this position, a ball will be again provided from the ball receptacle to gravitate upon said tee. This will cause the photoelectric proximity switch to become activated and again cause the tee to rise by the mode of operation already described. Cited mode of operation for lowering and elevating said tee 107 will prevail on a repetative basis as described, supra. As previously indicated, a pulse will be fed to the ball feed counter every time a ball is dislodged from said tee. Said plurality of pulses will be registered and when said count reaches the preset count, said ball feed counter will release a termination pulse to the monetary acceptor unit to terminate the vend. In so doing, contacts K2 will open to cut off power to the controller and to the photoelectric proximity switch. This means that when the last ball of the vend is dislodged from the tee, contacts K2 will open to terminate power to contacts A2 thus maintaining the tee in the elevated position.

To switch from Fairway Shot" to Tee Shot selection during the vend, the golfer depresses the "Tee Shot" selection pushbutton PB-3. Since the tee 107, with a ball thereupon,is in the intermediate ball hitting position before depressing of PB-3, photoelectric proximity siwtch contacts A1 will be closed and A2 will be open. Therefore, depressing of said pushbutton PB-3 will actuate latch relay coils C and L. This will cause relay contacts C2, C3, and L1 to open, and contacts C1 and L2 to close. Now, with contacts A1, C1, and closed, power will be conveyed to gearmotor 112 to drive the ball elevating means upwardly until two-way cam 121 actuates switch contacts 125 open. With said contacts 125 open, power will be terminated to said gearmotor and the tee 107 will be stopped at the uppermost ball hitting position. Now, after the ball is dislodged from the tee, subsequent operation of the apparatus will follow the same sequence described under Tee Shot selection mode of operation and the tee will now reciprocate between the ball receiving position and the uppermost ball hitting position as described.

In switching from Tee Shot to Fairway Shot selection during the vend, it must be discerned that the condition of relay and switch contacts will be initially as described under the Tee Shot" selection mode of operation with vend initiated so that contacts K1 and K3 will be open and contacts K2 will be closed. To recapitulate, contacts Cl and L2 will be initially closed and contacts C2, C3 and L1 will be initially open. Upon depressing of the Fairway Shot pushbutton PB-4, contacts C2 and C3 will close while contacts C] will open. The condition of contacts L1 and L2 will be unaffected because during the vend contacts K3 will be open and power cannot be conveyed to latch relay coil Lto induce switch-over of said contacts. It now becomes apparent that the function of latch relay L-L' is to act as a monitor to divert power during said Tee Shot to Fairway Shot" switch-over through the alternate branch line containing relay contacts D11 and L2, and switch contacts 124B. Said alternate branch will provide power to gearmotor 112 such that tee 107 will be lowered until said contacts 1248 are actuated open to stop said tee in the fairway shot position. When the ball is dislodged from said tee 107, contacts A2 will close to direct power through switch contacts 123A to energize the gearmotor to drive the ball elevating means downwardly. When two-way cam 121 opens said contacts 123A, the gearmotor will be de-energized to stop said tee in the lowermost ball receiving position. When said switch 123 is actuated, switch contacts 123B of said single poly double throw switch will close. Closing of said contacts 1238 will direct power through relay contacts C3 and D4 to energize latch relay coil L to open contacts L2 and close contacts Ll,thus activating the other branch line leading from relay contacts C2 through contacts L1 and switch contacts 124A to said gearmotor 112. Therefore, said switch-over had reverted the control circuit back to that depicted in FIG. 7 for Fairway Shot selection with vend initiated. Now, when a ball is dislodged from said tee 107, the apparatus will persue the mode of operation previously described under Fairway Shot selection mode of operation such that subsequent tee reciprocation will be between the ball receiving position and intermediate ball hitting position as disclosed.

For Golf Game selection as the mode of operation, the patron depresses only the Golf Game" pushbutton. Tee shot and fairway shot tee positioning will be provided automatically according to a predetermined sequence dictated by programming means such as the punched tape programmer.

Momentary depressing of the Golf Game Pushbutton PB-Z will energize latch relay coil D' to open contacts D1, D2, D4, D5, D11 and close contacts D3, D6, D7, D8, D9, and D10. Opening of said contacts D1, D2, D4, D5, and D11 will isolate the Fairway Shot" and Tee Shot pushbuttons from the circuit so that accidental depressing of said pushbuttons cannot affect the tee elevating sequence provided by the punched tape programmer 130. Closing of said contacts D3, D6, D7, D8, D9, and D will operatively connect said punched tape programmer into the circuit to provide for automatic positioning of said tee. The tape of said programmer is punched with control information such that holes in one channel represent the tee shot control function and holes in a second channel represent the fairway shot control function.

Placement of the proper amount of money in the monetary acceptor unit 118 will initiate the vend causing contacts K1 and K3 to open and contacts K2 to close. Opening of contacts Kl will isolate pushbuttons PB-l and PB-2 from the circuit so that selection switching is not possible after vend initiation. Closure of contacts K2 will provide power to the photoelectric proximity switch 127. With no ball on the elevated tee, contacts A2 will be in the closed position thus allowing power to proceed through the lowermost position sensing switch contacts to the prime mover to drive the ball elevator means downward. The tee will therefore be lowered until the two-way cam actuates said position switch contacts open to cut off power to the said prime mover and stop said tee in the lowermost ball receiving position. While in this position, a ball from ball receptacle 102 will'be automatically released to gravitate upon the tee. This will cause said photoelectric proximity switch to become activated and compel contacts A1 to close and A2 to open. Now, with the punched tape programmer in operation, the tape reader senses the hole in the first line of the tape and effectuates energization of either the tee shot latch relay coil C or the fairway shot latch relay coil C, depending on which channel the hole appears. If the tee shot relay coil C is energized, the load contacts Cl will close and direct power from contacts Al through the uppermost position sensing switch contacts to the prime mover and drive the ball elevator means to tee height position. If the fairway shot relay coil C'is energized, the load contacts C2 will close and direct power from contacts Al through the intermediate position switch contacts to the prime mover to drive the ball elevating means to fairway height position.

When the ball is dislodged from the tee, the photoelectric proximity switch 127 will operate to provide a pulse through terminal 9, open contacts A1, and close contacts A2. Said pulse from terminal 9 will be fed to the ball feed counter module 129 to register a count therein, and to the stepping drive of the punched tape programmer to advance the tape through the reader one line to provide the next tee height positioning command by again energizing either relay coil C or C. Meanwhile, contacts A2 will cause power to be directed through the lowermost position sensing switch contacts to the prime mover to drive the ball elevating means downward until the two-way cam contacts and opens said switch contacts to terminate power to said prime mover and stop the said tee in the ball receiving position. While in this position, a ball from ballreceptacle 102 will be provided to said tee thus causing the said photoelectric proximity switch to again close contacts A1 and open contacts A2. Now, depending on which one of said relay coils was energized when the tape was indexed to the second line, power will again be directed through either contacts C1 or C2 to energize the prime mover and drive the ball elevating means upward to either the tee height position or the fairway height position by the mode of operation previously explained for elevating said tee. This cited mode of operation for lowering and elevating the tee will prevail on a repetative basis every time a ball is dislodged from said tee. Termination of the vend will occur when the count registered on said ball feed counter reaches its preset count. When this occurs, said counter will release a termination pulse to the momentary acceptor 118 to terminate the vend. In so doing, contacts K2 will operate to terminate power to the controller 128 and the photoelectric proximity switch 127, thus stopping the tee in the elevated position. At termination of said vend, the programming tape will revert back to its initial starting point ready for re-cycling when another vend is initiated.

ll. Second Embodiment (see FIGS. 1, 4, 5, 6, and 0) This embodiment is composed essentially of a ball dispensing means 117, a ball receptacle 102, and a ball teeing means 200 interconnected in similar manner to the first embodiment. The base means of said ball teeing means is defined essentially by cup assembly 204 to which a mounting plate 205 is fixedly attached. Said cup assembly 204 has a ball inlet aperture 206 located within its cylindrical sidewall for mounting of ball receptacle 102 in depending relation therefrom and in registry with said aperture 206, an opening within the bottom for the journalling of both the upper portion of rack 210 and stem 202 which has tee 207 secured thereto, and an opening 208 at the top to provide for ball exit when placed in registry with the opening within floor 101.

Tee 207 is fixedly mounted to the top of said stem 202 whcih is reciprocably mounted'within the bottom opening of said cup assembly 204. The lower portion of said stem 202 is slidably mounted within rack cavity 201 with compression spring 217 maintaining said tee 207 a fixed distance away from the top of rack 210 which is also reciprocably mounted within the bottom opening of said cup assembly 204. Centrally and fixedly mounted to the top of said stem 202, and in depending manner within the central opening of said tee 207, is the ball sensing means such as photoelectric switching sensor lens assembly 209. The fiber-optic light guide 214 extending from said lens assembly 209 is disposed downwardly through stem 202 and proceeds through a clearance hole within said rack 210 to emerge from the bottom thereof. Said guide 214 is secured to the bottom of stem 202 by strain relief bushing 218.

Fixedly mounted to the bottom end of rack 210 is bracket 220. Fastened to said bracket is an actuator such as solenoid 229 having its plunger 230 in alignment with said light guide 214 emerging from the clearance hole within said rack. Said light guide is secured to plunger 230 by fastener 222 such that said plunger extends from the solenoid body by an amount equivalent to the height a ball is teed up for a tee shot. Fixedly mounted to the non-toothed side of rack 210 is stop pin 226 which is so disposed as to contact upper stop 325 and lower stop 227 when said rack is reciprocated. Said lower stop is fixedly mounted to mounting plate 205 such that said stop pin is in contact therewith when tee 207 is in ball receiving position such as shown. The upper stop is fixedly mounted to said plate 205 above said lower stop at such a distance that tee 207 will be in tee shot position when said rack is elevated such that said stop pin contacts said upper stop 225.

Gearmotor 212 is fixedly mounted at a set distance from mounting plate 205 by spacers 223. Said spacers are of such length as to permit coupling 224, such as a rubber tube, to connect shaft 215 to the gearmotor shaft such as shown. Said shaft 215 is journalled within bearing 220 located in mounting plate 205, and bearing 219 located in bearing plate 221. Said bearing plate is fixedly mounted to said mounting plate 205 such that said bearings 219 and 220 are in proper alignment with said gearmotor shaft. Fixedly mounted to shaft 215 between said bearing plate 221 and said mounting plate I 205 is gear 211 which is drivably engaged with said re ciprocally mounted rack 210. Shaft 216 journalled within flanged guide roller 213 is fixedly secured to mounting plate 205. Said guide roller is rollably engaged with the non-toothed side of said rack so that the center distance between shaft 216 and shaft 215 is such that said rack 210 can be freely reciprocated between said gear 211 and said roller 213.

FIG. 8 depicts the electric controls set on the Golf Practice with Fairway Shot selection as the mode of operation for the second embodiment of the invention. Momentary depressing of pushbutton PB-A will energize latch relay coil X to close contacts X1, X2, X4, and open contacts X3, X5, X6, X7, and X8. Then momentary depressing of pushbutton PB-D will convey a signal through X4 to energize latch relay coil Y to close contacts Y1.

Upon placement of the required money in the monetary acceptor unit 118, the vend will be initiated causing contacts K1 to open and K2 to close. Opening of contacts K1 will terminate power to the Golf Practice" and Golf Game selection branch circuit. Closing of contacts K2 will direct power to the prime mover control circuit through terminal '8 of the photoelectric proximity switch 127. With no ball on tee 207, contacts A2 will be in the closed position and A1 in the open position. Now, power from said terminal 8 will be directed through contacts A2 to energize gearmotor 212 to drive the ball elevating means downward to the ball receiving position. Rack 210 will therefore descend until stop pin 226 abuts lower stop 227 to stop said rack movement and stall out gearmotor 212. Now, it can also be readily discerned that power will be directed through Y1 to energize solenoid 229. Energizing of said solenoid will pull light guide 214 downward to compress spring 217 and effectuate position of stem 202 with tee 207 to its lowermost position within cavity 201 of rack 210. Said solenoid will remain energized during the Fairway Shot" selection mode of operation. With the tee in the lowermost ball receiving position, a ball will be provided from the ball receptacle 102 to gravitate thereupon. This will cause the photoelectric proximity switch 127 to become activated to close contacts Al and open contacts A2. Power will now be directed through contacts A1 to energize gearmotor 212 to drive the ball elevating means upwardly. Rack 210 will therefore rise until stop pin 226 abuts upper stop 225 to stop rack movement and stall out said gearmotor 212 to place the tee in the intermediate ball hitting position.

Upon dislodging of ball 203 from tee 207, the photoelectric proximity switch 127 will operate to provide a pulse through terminal 9, open contacts A1, and close contacts A2. Said pulse from terminal 9 will be fed to the ball feed counter module 129 to register a count therein. Now, the said tee will be again lowered by the mode of operation explained, and the cited modes of operation for lowering and elevating said tee 207 will prevail on a repetative basis as described supra. As previously indicated, a pulse will be fed to the ball feed counter module 129 every time a ball is dislodged from said tee. Said plurality of pulses will be registered and when said count reaches the preset count, said counter will release a termination pulse to the monetary acceptor unit 118 to terminate the vend. in so doing, contacts K2 will open to terminate power to the controller 128 and to said photoelectric proximity switch 127. This means that when the last ball of the vend is dislodged from the tee, contacts K2 will open to terminate power through contacts A2 thus maintaining the tee in the elevated position.

It is to be noted that in this embodiment flexible coupling 224 can be replaced by a magnetic slip coupling 231 so that gearmotor 212 does not have to be stalled when said stop pin abuts either the upper or lower stops. Said gear-motor will continue running with said coupling providing a slipping action so that the couplings magnetic field will hold the ball elevating means in the required position during coupling slip.

Golf Practice with Tee Shot" selection as the mode of operation is obtained by momentary depressing of pushbutton PB-A to energize latch relay coil X to close contacts X1, X2, X4 and open contacts X3, X5, X6, X7 and X8. Then momentary depressing of pushbutton PB-C will convey a signal through contacts X2 to energize latch relay coil Y to open contacts Y1.

Upon placement of the required money in the monetary acceptor unit 118, the vend will be initiated causing contacts K1 to open and K2 to close. Opening of contacts K1 will terminate power to the Golf Practice and Golf Game selection branch circuit. Closing of contacts K2 will direct power to the gear-motor control circuit through terminal 8 of the photoelectric proximity switch 127. With no ball on tee 207, contacts A2 will be in the closed position and A1 in the open position. Now, power from said terminal 8 will be directed through contacts A2 to energize gearmotor 212 to drive the ball elevating means downward. Tee 207 will therefore descend until stop pin 226 abuts lower stop 227 to stop rack movement and stall out gear-motor 212. With no power to solenoid 229, spring 217 will move to its extending position to effectuate positioning of stem 202 with tee 207 to its uppermost position within cavity 201 of rack 210. Solenoid 229 will remain de-energiz'ed during the Tee Shot selection mode of operation with plunger 230 extended from within solenoid 229. With tee 207 in the lowermost ball receiving position, a ball will be provided from the ball receptacle 102 to gravitate upon said tee. This will cause the photoelectric proximity switch 127 to become activated to close contacts A1 and open contacts A2. Power will now be directed through contacts A1 to energize gearmotor 212 to drive the ball elevating means upwardly. Rack 210 will therefore rise until stop pin 226 abuts upper stop 225 to stop rack movement and stall out said gearmotor 212 to place said tee in the uppermost ball hitting position.

Upon dislodging of ball 203 from tee 207, the photoelectric proximity switch 127 will operate to provide a pulse through terminal 9, open contacts Al, and close contacts A2. Said pulse from terminal 9 will be fed to the ball feed counter module 129 to register a count therein. Now, the said tee will be again lowered by the mode of operation explained, and the cited modes of operation for lowering and elevating said tee 207 will prevail on a repetitive basis as described supra. As previously indicated, a pulse will be fed to the ball feed counter module 129 every time a ball is dislodged from said tee. Said plurality of pulses will be registered and when said count reaches the preset count, said counter will release a termination pulse to the monetary acceptor unit 118 to terminate the vend. In so doing, contacts K2 will open to terminate power to the controller 128 and to said photoelectric proximity switch 127. This means that when the last ball of the vend is dislodged from the tee, contacts K2 will open to terminate power through contacts A2 thus maintaining the tee in the elevated position.

The switch from Fairway Shot" to Tee Shot selection during the vend, the golfer depresses the Tee Shot" pushbutton PB-C. Since tee 207, with a ball thereupon, is in the intermediate ball hitting position before depressing of PB-C, photoelectric proximity switch contacts AI will be closed and A2 will open. Therefore, depressing of said pushbutton PB-C will actuate latch relay coil Y to open contacts Yl. Opening of contacts Y1 will cut off power to solenoid 229. With no power to said solenoid, spring 217 will move to its extended position to effectuate positioning of stem 202 with tee 207 to its uppermost position within cavity 201 of rack 210 thus switching said tee elevation to the uppermost ball hitting position. Said solenoid will now remain de-energized during the Tee Shot selection mode of operation withplunger 230 extended from within solenoid body 229. Now, after the ball is dislodged from the tee, subsequent operation of the apparatus will follow the same sequence described under Tee Shot" selection mode of operation, and the tee will now reciprocate between the lowermost ball receiving position and the uppermost ball hitting position. To switch from "Tee Shot" to Fairway Shot'selection during the vend, the golfer depresses the Fairway Shot" pushbutton PB-D. Since tee 207, with a ball thereupon, is in the uppermost ball hitting position before depressing of PB-D, photoelectric proximity switch contacts A1 will be closed and A2 will be open. Therefore, depressing of PB-D will actuate latch relay coil Y to close contacts Y1. Closing of said contacts Yll will energize solenoid 229, to pull plunger 230 within solenoid 229. Retraction of said plunger will cause spring 217 to compress and effectuate position ing of stem 202 with tee 207 to its lowermost position within cavity 201 of rack 210 thus switching said tee elevation to the intermediate ball hitting position. Said solenoid will now remain energized during the Fairway Shot" mode of operation thus holding said stem 202 in a lowermost position within said cavity 201. Now, after the ball is dislodged from the tee, subsequent operation of the apparatus will follow the same sequence described under Fairway Shot selection mode of operation, and the tee will now reciprocate between the lowermost ball receiving position and the intcrmediate ball hitting position.

For Golf Game selection as the mode of operation, the patron depresses only the Golf Game" pushbutton. Tee shot and fairway shot golf tee positioning will be provided automatically according to a predetermined sequence dictated by programming meano such as the punched tape programmer 130.

Momentary depressing of the Golf Game pushbutton PB-B will energize latch relay coil X to open contacts X1, X2, X4 and close contacts X3, X5, X6, X7, and X8. Opening of said contacts X1, X2, and X4 will isolate the Fairway Shot and Tee Shot pushbuttons from the circuit so that accidental depressing of said pushbuttons cannot affect the tee elevating se quence provided by the punched tape programmer 130. Closing of said contacts X3, X5, X6, X7, and X8 will operatively connect said punched tape programmer into the circuit to provide for automatic positioning of said tee. The tape of said programmer is punched with control information such that holes in one channel represent the tee shot control function and holes in a second channel represent the fairway shot control function.

Placement of the proper amount of money in the monetary acceptor unit 118 will initiate the vend causing contacts Kl to open and K2 to close. Opening of contacts Kl will isolate push-buttons PB-A and PB-B from the circuit so that selection switching is not possible after vend initiation. Closure of contacts K2 will provide power to the photoelectric proximity switch 127 and the motor control circuit. With no ball on the elevated tee, contacts A2 will be in the closed position thus conveying power to gearmotor 212 to drive the ball elevating means downward. Control of said ball elevating means will now follow the same sequence described for switching from Tee Shot" to Fairway Shot and from Fairway Shot to Tee Shot" modes of operation with said switching provided automatically by punched tape programmer 130.

In the Golf Game mode of operation, the function of pushbuttons PB-C and PB-D is replaced by said punched tape programmer. With said programmer in operation, the tape reader senses the hole in the first line of the tapeand effectuates energization of either the tee shot latch relay coil Y or the fairway shot latch relay coil Y, depending on which channel the hole appears. lf coil Y is energized, load contacts Y1 will open to set the elevation of stem 202 for tee shot operation. If coil Y' is energized, load contacts Y1 will close to set the elevation of stem 202 forfairway shot operation. Now, as previously mentioned, reciprocation of tee 207 will depend upon whether or not there is a ball thereupon to effectuate operation of contacts Al and A2 of said proximity switch 127. With no ball on said tee, contacts AI will be closed thereby causing gearmotor 212 to drive said tee downward. With aball on said tee,

contacts AI will be closed thereby causing gearmotor.

212 to drive said tee upward.

Everytime a ball is dislodged from the tee, a pulse from the proximity switch 127 will beprovided to terminal 15 of controller 128 and to terminal 20 of the ball feed counter module 129. The pulse to said counter will register a count therein, and the pulse to said controller will be directed to the stepping drive of the punched tape programmer to advance the tape through the reader one line to provide the next tee height positioning command for energizing either relay coil Y or Y. Cited mode of operation for lowering and elevating the tee and adjusting of stem position within rack cavity will prevail on a repetative basis and termination of the vend will occur when the count registered on said counter 129 reaches its preset count. When this occurs, said counter will release a termination pulse to the monetary acceptor unit 118 to terminate the vend. In so doing, contacts K2 will open to terminate power to the controller 128 and the photoelectric proximity switch 127, thus stopping the tee in the elevated position. At termination of said vend, the programming tape will revert back to its initial starting point ready for re-cycling when another vend is initiated.

It is to be noted that in both embodiments there exists means to provide automatic switching between a lowermost-to-intermediate positional mode of operation, and a lowermost-to-uppermost positional mode of operation. This means that when the ball elevating means is reciprocating or set to reciprocate between the lowermost ball receiving position and the intermediate ball hitting position, it can be automatically switched for reciprocation between the lowermost ball receiving position and the uppermost ball hitting position, or vice versa.
